My invention relates to a new and useful smoke precipitating apparatusand particularly adapted for use in precipitating coal smoke.

The invention is so constructed as to o erate so as to utilize the`discharging e `ects of pointed surfaces of bodies vpossessing a. highelectric charge. It is known that by equipping a chimney or otherpassage-way of smoke with a plate and discliarging'pointspositionedopposite thereto and a proper diS- tance away from the plateand that by charging the apparatus to a high potential, precipitation ofsuspended particles from smoke l5 can be brought about. However, whenthe plate becomescovered with soot, the apparatus becomes ineffectiveand it is to overcome this disadvantage which is one of the objects 20of the present invention.4

vision of a smoke precipitating apparatus of thisaclas's which will besimple in structure, economical of manufacture and highly eihcient inuse.

Another object of the invention is the provision of a device which maybe easily and j quickly installed, inexpensive to operate and compact inits structure.

Other objects will appear hereinafter..

The invention consists inthe combination and arrangement of partshereinafter described and claimed.

The invention will be best understoodby a reference to the accompanyingdrawin 35 which forms a part of this specification an in which,

' zontally extended shaft 13 which projects through insulating bushings13 mounted in the walls 23 and 24^of a housing. Mounted so as to permitthe shaft 13 to project therethrough is a housing having walls 15 and18. 65 Projecting inwardly from the wall 15 is a cylindrical bracket 14in which is pitioned a spring 16 engaging a brush 20. A similar brush 21is in engagement with the spring 19 positioned in the cylindricalbracket 17 im which projects inwardly from the housing wall 18. 1n thelower part of this housing 1 have oil or a like liquid. Fixedly mountedon the shaft 13 so as to engage between and be engaged by the brushes 20andI 21 is a disc 5 22. The wall 24 of the housing is inwardly set as at25 and provided with a vertically extending continuation 26. A neck 28projects upwardly from the upper wall 27 of the housing embracing whichis the conduit or Hue 29 70 leading tothe blower 30, this blower beingoperated by the electric motor 31. Fixedly mounted on the shaft 13interiorly of the housing having the walls 23 and 24 is a disc 32. Aninsulating plate 33 serves to insu- 0 late the metallic plate 34 from.the wall 26.- Projecting outwardly from one face of the plate 24 so asto lie horizontally are metallic contact members or pins 36, preferablyformed from wire, these pins projecting through the layer of insulation35 which may be formed :from asbestos wool or other 'suitable insulatingmaterial. Formed in this layer 35 is a cavity 37 in which is positioned85 the enclosing housing' 38. Projecting inwardly-from the housing wall24 are brackets 39 and 40, each of which is constructed simi. larly. Aslot 41 is formed in each of the brackets, these brackets being providedwith channels 42and 43 as appears in Fig. 1 and Fig. 4'. Engaging in thechannels 43 and42 are trunnions 44 and 45, respectively, which projectoutwardly from the bearing 46 in which is journalled the shaft 47 of theroller 95 brush 48, this roller brush being held by the springs 46 inengagement with the face of the disc 32. This brush is rotated by theflexible shaft 109carrying the gear 110 Whlch meshes with the gear 111on the motor 68. 100

A simllar sealing block 52 is positionedaround the imsulating member 35. -A conduit 53 which 75 serves as a flueor chimney is divided into a pair of branches 54 and 55 whichcommunicate with the housing through the necks 56 and 57. Mounted in thelue 53 is a door 105 which is kept closed by the action of an 80electromagnet. In case the power should be accidentally cut off theelectromagnet will release the door. Springs set for such purpose willpush it wide open. The motive of such outlet is to give a way out to thesmoke for the time the power is olf and the blower still. The wires 58and 58 and 59 connect to a suitable source of electrical energy and leadto the transformer 60 which is electrically1 connected to the converter61 which serves to 90 5 transmit direct current to the discharge pointsthrough a wire 62. A wire 63 connects this converter to the brushes 20and 21 through the disc or plate 22 to the plate 32. The motors 68 and31 are connected to the source of 95 electrical energy in the usualmanner.

The motor 68 is connected by the belts 69 to the pulley 70 which isixedly mounted on the shaft 13. The motors 31 and 68 are wired as to themains in the regular way. A iexible shaft connects the rotary brush tothe motor 68. Where a large machine is used a small motor may be usedexclusively to rotate the brush, thus doing away with the flexibleshaft.

o In operation, as Vthe smoke is delivered up 105 the chimney 53, theelectric charge will cause a deposit of the smoke over the disc 32. Asthe disc 32 is rotated upon a rotation of the shaft 13, the brush 48will serve to prevent 4.5 accumulation of soot on the disc 32, thus prouno viding an eicient operative device at all times. l

While I have illustrated and described the w preferred form of myinvention, I do not wish to limit myself to the precise details oistructure shown but desire to avail myself of such variations andmodifications as come within the scope of the appended claim.

u Having thus described my invention, what no I claim as new and desireto secure by Letters Patent is:
